Definitions

  • Document EP 1990526 A2 discloses to apply, in between termination of an electromagnetic coil-voltage application equivalent to termination of a first fuel injection period and initiation of an electromagnetic coil-voltage application equivalent to initiation of a second fuel injection period subsequent to the first fuel injection period, the electromagnetic coil with a voltage at a level of not opening the valve to supply an intermediate current for the electromagnetic coil in the same direction as a direction of a drive current for opening the valve.
  • the present invention it is possible to shorten an interval between the first fuel injection period and the second fuel injection period subsequent to the first fuel injection period.
  • a fuel injection valve can be driven while the split injection is performed at reduced intervals.
  • a split injection control is executed either by allowing the ECU 120 to output a voltage application command pulse for supplying an intermediate current for split injection or by having the ECU 120 transmit the control constant to the EDU 121 to let the EDU 121 directly supply the intermediate current.
  • valve plug 114 leaves from the valve seat 118, so the fuel supplied into the fuel injection valve is injected from a plurality of injection holes 119 provided to an orifice plate 116.
  • the movable core 102 starts a valve closing sequence. Subsequently, before the displacement of the movable core 102 is reduced to 0 (zero) or less (namely, before the timing t 32 where the valve plug 114 sits on the valve seat 118, that is, before the timing when the engagement portion 301 of the movable core 102 is disengaged from the engagement portion 302 of the valve plug 114 to allow the movable core 102 to initiate its relative displacement in the valve closing direction with respect to the valve plug 114), an injection pulse 409 is turned on at t 31 , and thereby causing the high-voltage source to apply a high voltage 403 and supplying an intermediate current 407 to the electromagnetic coil 105.
